STRAW-STAGKING ATTACHMENT FOR THRASHlNG-MAGHINES.

SPECIFICATION forming part of Letters Patent No. 289,460, dated December 4, 1883. Application filed February 6,1883. (N model.)

To aZZwhom it may concern Be it known that we, CHARLES D. SPRAGUE,

of Ohilhowee, in the county of Johnson, State of Missouri, and PEARLEY J. Srnneon, of Higbee, in thecounty of Randolph and State tachments for ThrashingMachines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of our improvement, showing it secured to the rear end of a thrashing-machine. Fig. 2 is a top view of the turntable or frame, part broken away. Fig. 3 is a vertical section of same, taken on line 3 3, Fig. 2. Fig. 4 is a detail view of the top of the derrick. Fig. 5 is a vertical section takenon line 5 6, Fig. 2, showing the agitating-board in its lower position. Fig. 6 is a similar view with the board in its upper position. Fig. 7 is a detail side view, showing the driving belt or chain. Fig. 8 is a side view illustrating the manner of operating the folding leaves hereinafter described. view of same; and Figs. 10, 11, 12, and 13 are diagrams illustrating different positions of the leaves, Figs. 10 and 11 being side views and the other two figures being end views. Fig. 14 is a perspective view of the top of the derrick, showing the manner of attaching its supporting-rope, and showing a hood covering the pulley of the stacker-rope. Fig. 15 is an end view of the frame supporting the turntable, showing its adjustable legs.

Our invention relates to a straw-stacker to be attached to the rear end of athrashing-machine, and is adapted to be attached to machines of different width; and our invention consists in points of novelty hereinafter fully described and claimed.

Referring to the. drawings, A represents the rear end of a thrashing-machine, to which is secured a frame, B. The frame is preferably pivoted so that its rear end can be raised up, when moving the machine from one place to another, by means of chains or ropes B, secured to the frame and engaging over a hook,

Fig. 9 is an end B'---0ne on each side of the machine. The frame is shown secured to the sllls of the machine as the preferred manner of connecting it, and its outer portion issupported by legs B, (see Fig. 15,) pivoted to it, so that in case of uneven ground they may be adjusted as required. The forward or outer portion of the frame is preferably semicircular in form, (see Fig. 2,) and has two cross-beams, B E the latter of which forms the support of the bolster C of the turn-table, to which the stacker D is secured. The turn-table consists of the bolster O, cross-pieces O, and side pieces, 0", the stacker being preferably secured to the side pieces. (See Figs. 2, 5, 6, and 9.) The bolster O is secured to the cross timber or plece B by a sleeve, E, (see Fig. 3,) which allows the table to turn freely. J ournaled in this sleeve is a vertical shaft, F, with miter-wheels F F on its opposite ends, as shown, that F being the lower one, meshing into a similar wheel, G, on the inner end of a horizontal shaft, G, journaled in hangers H, depending from the cross-piece B on the outer end of which is a drive wheel or pulley, G which receives power from the machine. The other miter-wheel, F of the shaft F meshes into a similar wheel, I, of a horizontal shaft, I, having journal-bearing at one end in an upright, J, secured to the bolster, and at theother end in one of the sides .0 of the table. 1 (See Fig. 3.) 011 the outer end of the shaft I is a sprocket-wheel, I", which connects by a suitable chain or belt, I", with a similar wheel or pulley, K, of the shaft K of the stacker, which is journaled in thesides of the table.

Now, it will be seen that the table can be turned freely without interfering in the least with the working of the described gearing, and any side strain or end strain of the table is received by the sleeve E, and does not bind onthe shaft F and cause friction, preventing the shaft turning freely, and the shaft I being above the sills of the machine, the table can be turned to any angle desired-without the wheel on the end of shaft striking the sills, and. likewise our device can be used on machines of differ ent width, as the shafts G and I can be of any length required to suit the stacker of the machine. The turn-table is held to its adjustment by the downturned end of a rod, L, se cured to one of the cross-pieces O of the table, entering holes in a semicircular plate, L, secured to the cross-piece B of the supporting-frame. (See Figs. 2 and 3.) The bar or rod L extends out through one of the sides of the table, where it is turned up, engaging with a catch, L The table supports an agitatingframe, K, which receives the straw from the machine and delivers it to the stacker. This frame has a rearward, upward, and a downward retreating motion imparted to it for the purpose of carrying the straw forward, and also prevent it lodging on the lower end of the stacker. The upper surface of the frame is ribbed, being made of narrow strips overlapping each other. (See Figs. 2, 5, and (5.)

The frame is agitated in the following manner: M are arms pivoted by their lower ends to the sides of the table, (see Figs. 5 and 6,) and secured by their upper ends to the sides of the frame by bolts M. The bolts of the arms nearest the stacker also pass through pitmen N by means of holes 1, to allow for adj ustment, connected by their other ends to cranks 0 (see Fig. 2) of a shaft, 0, journaled in the sides of the table, and having a wheel or pulley, 0 on one end, (see Fig. 7,) over which the belt or chain 1 passes. Thus it will be seen that by turning the shaft 0 the described motion will be imparted to the frame K. The chain or belt I is kept taut'by a suitable idler, I. (See Fig. 7.)

S represents a shaft, which forms a stop for the frame, which enters a notch, Q, when the frame is in its lowest position. (See Figs. 5 and 6.)

We have shown the sides of the table provided with folding leaves R, which can be supported, as shown in Fig. 9, or either one folded down or both folded down, as shown in Figs. 12 and 13. Thus, when the table is turned with one of its sides to the machine, the leaf of this side is turned down, so as not to interfere with the straw being discharged from the machine onto the table, and to form a platform or landing over the operating devices. The leaves are operated by cams S S on the shaft S, having bearing in the sides of the table, with hand-wheels S on its outer ends. (See Figs. 8, 9, 10, 11, 12, and 13.) The cams are so located 011 the shaft that as one leaf is lowered the other is raised, (see Fig. 12,) or they can be both lowered, (see Fig. 13,) or both sustained, (see Fig. 9,) these different positions being given by simply turning the shaft.

T represents a derrick secured to the top of the machine, and supported by a guy-rope, T, secured to the machine and to a bail, T connected to the derrick. (See Fig. 14.) The derrick supports the stacker by a rope, U, made fast by one end to the stacker, passing up over a pulley, V, on top of the derrick, and down to a Windlass, V, located at the foot of the derrick, by which the stacker can be raised .or lowered. The top of the derrick should be over or nearly over the center 011 which the table turns, so that turning the table will have no effect on the stacker through the rope U. The pulley V is journaled in a hood, V, which extends some distance toward the stacker, as shown, or toward the Windlass, if desired, and through which, of course, the rope passes, the object being to form a leverage for the rope in turning the pulley as the turn-table and stacker are moved to the right and left, delivering the straw to different parts of the stack. The table and stacker can be turned by any suitable means.
